	\paragraph{Syntax}

\begin{verbatim}
[C,R] = acf(V,...)
\end{verbatim}

\paragraph{Input arguments}

\begin{itemize}
\tightlist
\item
  \texttt{V} {[} VAR {]} - VAR object for which the ACF will be
  computed.
\end{itemize}

\paragraph{Output arguments}

\begin{itemize}
\item
  \texttt{C} {[} namedmat \textbar{} numeric {]} - Auto/cross-covariance
  matrices.
\item
  \texttt{R} {[} namedmat \textbar{} numeric {]} -
  Auto/cross-correlation matrices.
\end{itemize}

\paragraph{Options}

\begin{itemize}
\item
  \texttt{\textquotesingle{}applyTo=\textquotesingle{}} {[} logical
  \textbar{} \emph{\texttt{@all}} {]} - Logical index of variables to
  which the \texttt{\textquotesingle{}filter=\textquotesingle{}} will be
  applied; \texttt{@all} means all variables.
\item
  \texttt{\textquotesingle{}filter=\textquotesingle{}} {[} char
  \textbar{} \emph{empty} {]} - Linear filter that is applied to
  variables specified by `applyto'.
\item
  \texttt{\textquotesingle{}matrixFmt=\textquotesingle{}} {[}
  \emph{\texttt{\textquotesingle{}namedmat\textquotesingle{}}}
  \textbar{} \texttt{\textquotesingle{}plain\textquotesingle{}} {]} -
  Return matrices \texttt{C} and \texttt{R} as either
  \href{namedmat/Contents}{\texttt{namedmat}} objects (i.e.~matrices
  with named rows and columns) or plain numeric arrays.
\item
  \texttt{\textquotesingle{}nFreq=\textquotesingle{}} {[} numeric
  \textbar{} \emph{\texttt{256}} {]} - Number of equally spaced
  frequencies over which the
  \texttt{\textquotesingle{}filter=\textquotesingle{}} is numerically
  integrated.
\item
  \texttt{\textquotesingle{}order=\textquotesingle{}} {[} numeric
  \textbar{} \emph{\texttt{0}} {]} - Order up to which ACF will be
  computed.
\item
  \texttt{\textquotesingle{}progress=\textquotesingle{}} {[}
  \texttt{true} \textbar{} \emph{\texttt{false}} {]} - Display progress
  bar in the command window.
\end{itemize}
